Not sure, there is no graph with it. I just edited the question to fix the formatting and to add in info that got cut off when iI pasted it in.

Does anyone know where the a in front of the parentheses for the LCD : a(a+5)(a-6) came from?

lukranit [14]

Answer:

See below

Step-by-step explanation:

If you factor $a^2-a-30$ you get $\left(a^2+5a\right)+\left(-6a-30\right)$

= $a(a+5)-6(a+5)$

= $a(a+5)(a-6)$

That's where the a comes in

Not sure if that answers your question

Create the equation used to graph this graph:

Nuetrik [128]

Answer:

$(y+4)^2=-4(x-2)$ or $x=-\frac{1}{4}(y+4)^2+2$

Step-by-step explanation:

we know that

The general equation of a horizontal parabola open to the left is equal to

$(y-k)^2=-4p(x-h)$

where

(h,k) is the vertex of the parabola

p is the focal distance (distance from the vertex to the focus)

In this problem we have

The vertex is the point (2,-4)

$(h,k)=(2,-4)$

The Focus is the point F(1,-4)

the focal distance p=2-1=1 ---> distance from the vertex to the focus

substitute in the formula

$(y+4)^2=-4(1)(x-2)$

$(y+4)^2=-4(x-2)$

$x=-\frac{1}{4}(y+4)^2+2$

Clara created the poster shown below:

Answer:

$length=4\ cm\\width=6\ cm$

Step-by-step explanation:

Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:

$w_1=24\ cm\\l_1=16\ cm$

In order to calculate the dimensions of the rectangular at $\frac{1}{4}$ times its current size, you need to multiply the original lenght by $\frac{1}{4}$ and multiply the original width by $\frac{1}{4}$ .

Knowing this, you get:

$w_2=w_1\frac{1}{4}\\\\w_2=(24\ cm)(\frac{1}{4})\\\\w_2=6\ cm\\\\\\l_2=l_1\frac{1}{4}\\\\l_2=(16\ cm)(\frac{1}{4})\\\\l_2=4\ cm$
